[0002] In the lithium-ion battery cell stacking process, stacking robots are used to sequentially transport the cathode and anode electrodes from the conveyor line to the stacking table. As production efficiency demands increase, stacking speeds are also rising, placing higher demands on the handling speed of the stacking robots. However, due to the poor stability of conventional stacking robots, they are prone to significant vibrations during high-speed stacking, thus affecting the stacking accuracy. Utility Model Content

[0003] Therefore, it is necessary to provide a conveying device and stacking equipment that can improve the stacking accuracy in order to address the above problems.

[0004] A conveying device includes a driving mechanism, an adsorption mechanism, and a damping mechanism. The adsorption mechanism is installed at the driving end of the driving mechanism.

The moving end of the lateral moving component can reciprocate along a first direction, and the moving end of the lifting component can rise and fall along a second direction. The adsorption mechanism is installed on the moving end of the lateral moving component or the lifting component.

[0006] In one embodiment, the lateral movement assembly includes a linear motor module and a mounting base, the lifting assembly includes a voice coil motor and a mounting bracket, the mounting base is mounted on the mover of the linear motor module, the voice coil motor is disposed on the mounting base, the mounting bracket is slidably mounted on the mounting base along the second direction and connected to the drive shaft of the voice coil motor, and the adsorption mechanism is mounted on the mounting bracket.

[0007] In one embodiment, the mounting bracket is mounted to the mounting base via at least two slide rails extending along the second direction.

[0008] In one embodiment, a connecting mechanism is also included, wherein the adsorption mechanism is mounted to the drive end of the drive mechanism via the connecting mechanism. The connecting mechanism includes at least three trusses arranged in a triangular pattern, with one end of each truss fixed to the drive end of the drive mechanism and the other end fixed to the adsorption mechanism.

[0009] In one embodiment, the adsorption mechanism includes a transfer plate, an elastic floating component, a support plate, and an adsorption element. The adsorption element is mounted on the support plate, the transfer plate is connected to the transfer plate via the elastic floating component, and the transfer plate is mounted on the drive end of the drive mechanism.

[0010] In one embodiment, the elastic floating assembly includes a guide, a compression spring, and a limiting block. The adapter plate is slidably mounted on the support plate via the guide. The compression spring is disposed between the adapter plate and the support plate. The limiting block is mounted on the guide and presses the adapter plate against the compression spring.

[0029] Please see Figure 1 This utility model provides a conveying device 10 and a stacking device (not shown in the figure). The stacking device includes the conveying device 10 and a stacking table (not shown in the figure).

[0030] The conveying device 10 can pick up electrode sheets and transport them to the stacking table. Specifically, the electrode sheets used to produce battery cells include anode electrode sheets and cathode electrode sheets. Generally, two conveying devices 10 are provided, located on opposite sides of the stacking table. The two conveying devices 10 can alternately transport the cathode electrode sheets and anode electrode sheets to the stacking table, thereby achieving alternating stacking of cathode and anode electrode sheets. Of course, the conveying device 10 can also be applied to other fields to pick up and transport other sheet materials.

[0031] Specifically, in one embodiment of the present invention, the conveying device 10 includes a driving mechanism 100, an adsorption mechanism 200, and a damping mechanism 300.

[0032] The adsorption mechanism 200 can pick up the electrode sheet using methods such as negative pressure adsorption and electrostatic adsorption. Furthermore, the adsorption mechanism 200 is installed at the drive end of the drive mechanism 100, which can drive the adsorption mechanism 200 to move along a set trajectory, thereby transporting the electrode sheet. The damping mechanism 300 includes a damping element 310, with one end of the damping element 310 connected to the adsorption mechanism 200 and the other end connected to the drive end of the drive mechanism 100.

[0033] The damping element 310 can apply a damping force between the adsorption mechanism 200 and the driving mechanism 100. Specifically, the damping element 310 can be configured as a spring, a cylinder, or a hydraulic cylinder. In this embodiment, the damping mechanism 300 includes two supports 320, which are respectively disposed at the driving ends of the adsorption mechanism 200 and the driving mechanism 100, and the two ends of the damping element 310 are rotatably mounted on the two supports 320.

[0034] The two ends of the damping element 310 can be connected to two supports 320 via pins and hinges, so that the damping element 310 can rotate relative to the supports 320. In this way, the angle of the damping element 310 relative to the adsorption mechanism 200 and the drive mechanism 100 can also be adaptively adjusted in actual application, thereby avoiding torsional deformation of the damping element 310.

[0035] Since the damping element 310 provides damping force, it can play a role in buffering and vibration reduction. Even if the drive mechanism 100 moves at high speed during the stacking process, the vibration generated by the adsorption mechanism 200 will be significantly reduced compared with the traditional stacking robot, so that the adsorption mechanism 200 and the electrode it picks up can maintain high stability during high-speed stacking.

[0036] In this embodiment, the drive mechanism 100 includes a transverse component 110 and a lifting component 120. The moving end of the transverse component 110 can reciprocate along a first direction, and the moving end of the lifting component 120 can rise and fall along a second direction. The adsorption mechanism 200 is installed on the moving end of the transverse component 110 or the lifting component 120.

[0037] Specifically, the lifting assembly 120 can be positioned at the moving end of the horizontal moving assembly 110, and the adsorption mechanism 200 can be mounted on the moving end of the lifting assembly 120; alternatively, the horizontal moving assembly 110 can be positioned at the moving end of the lifting assembly 120, and the adsorption mechanism 200 can be mounted on the moving end of the horizontal moving assembly 110. Under the combined action of the horizontal moving assembly 110 and the lifting assembly 120, the adsorption mechanism 200 can move within two degrees of freedom, thus facilitating the handling of the electrode sheet. Optionally, the first direction and the second direction are perpendicular to each other. In practical applications, the first direction can be horizontal, while the second direction can be vertical.

[0038] Furthermore, in this embodiment, the transverse component 110 includes a linear motor module 111 and a mounting base 112, and the lifting component 120 includes a voice coil motor 121 and a mounting bracket 122. The mounting base 112 is mounted on the mover of the linear motor module 111, the voice coil motor 121 is disposed on the mounting base 112, the mounting bracket 122 is slidably mounted on the mounting base 112 along the second direction and connected to the drive shaft of the voice coil motor 121, and the adsorption mechanism 200 is mounted on the mounting bracket 122.

[0039] The mover of the linear motor module 111 can drive the mounting base 112 to reciprocate along a first direction, and the drive shaft of the voice coil motor 121 can drive the mounting frame 122 to move up and down along a second direction. The two work together to move the mounting frame 122 in both the first and second directions, thereby driving the adsorption mechanism 200 to move along both directions. Both the linear motor module 111 and the voice coil motor 121 have the characteristics of fast acceleration and fast response, thus enabling high-speed movement of the adsorption mechanism 200, making the conveying device 10 suitable for high-speed stacking. Furthermore, the linear motor module 111 and the voice coil motor 121 also have advantages such as smooth motion, simple structure, and high precision, thus further improving the stability of the adsorption mechanism 200 during high-speed stacking.

[0040] Furthermore, since the load capacity of the voice coil motor 121 is smaller than that of the linear motor module 111, the lifting assembly 120 is mounted on the mounting base 112, while the adsorption mechanism 200 is mounted on the mounting bracket 122. In this way, the voice coil motor 121 only needs to bear the weight of the adsorption mechanism 200, which helps to further improve the response and operating speed of the voice coil motor 121.

[0041] More specifically, the transverse assembly 110 also includes a mounting plate 113, a cable chain bracket 114, and a cable chain 115. The mounting base 112 is fixed to the mounting plate 113, which is mounted on the linear motor module 111. The cable chain bracket 114 is mounted on the outside of the mounting base 112. The mover of the linear motor module 111 moves along a first direction on the stator, thereby driving the mounting base 112 and the cable chain 115 to reciprocate along the first direction via the mounting plate 113.

[0042] Furthermore, in this embodiment, the mounting bracket 122 is mounted to the mounting base 112 via at least two slide rails 123 extending along the second direction. A reinforcing block (not shown) may also be provided between the slide rails 123 and the mounting base 112 to increase the connection strength between the slide rails 123 and the mounting base 112. The slide rails 123 make the mounting bracket 122 more stable when sliding along the second direction, thereby further improving the stability of the adsorption mechanism 200.

[0043] Furthermore, in this embodiment, the conveying device 10 also includes a connecting mechanism (not shown in the figure), and the adsorption mechanism 200 is installed on the driving end of the driving mechanism 100 through the connecting mechanism. The connecting mechanism includes at least three trusses 410 arranged in a triangular pattern, and one end of each truss 410 is fixed to the driving end of the driving mechanism 100, and the other end is fixed to the adsorption mechanism 200.

[0044] The three triangularly distributed trusses 410 enhance the connection strength between the adsorption mechanism 200 and the drive end of the drive mechanism 100, thereby improving the stability of the adsorption mechanism 200. Furthermore, compared to other connection methods, the structure of the three trusses 410 also meets lightweight design requirements, reducing the load during movement. Thus, the speed and stability of the adsorption mechanism 200 are further guaranteed during the movement of the adsorption mechanism 200 driven by the drive mechanism 100.

[0045] Please refer to the following: Figure 2 and Figure 3 In this embodiment, the adsorption mechanism 200 includes a transition plate 210, an elastic floating component 220, a support plate 230, and an adsorption member 240. The adsorption member 240 is installed on the support plate 230. The transition plate 210 is connected to the transition plate 210 through the elastic floating component 220. The transition plate 210 is installed on the drive end of the drive mechanism 100.

[0046] The adapter plate 210 can be connected to the drive end of the drive mechanism 100 via threaded fastening or other means. Specifically, the adapter plate 210 is connected to the drive end of the drive mechanism 100 through a truss 410. The adsorption member 240 is used to adsorb the electrode sheet, and the elastic floating component 220 enables the support plate 230 to float elastically relative to the adapter plate 210. During the electrode sheet handling process, the support plate 230, by floating elastically relative to the adapter plate 210, can also play a vibration damping role, thereby further improving the stability of the adsorption member 240 and the adsorbed electrode sheet. In other words, under the combined action of the elastic floating component 220 and the damping mechanism 300, the adsorption member 240 can achieve dual vibration damping, thereby significantly improving the stability of the electrode sheet during high-speed stacking.

[0047] Specifically, in this embodiment, the elastic floating component 220 includes a guide 221, a compression spring 222, and a limiting block 223. The adapter plate 210 is slidably mounted on the support plate 230 via the guide 221. The compression spring 222 is disposed between the adapter plate 210 and the support plate 230. The limiting block 223 is mounted on the guide 221 and presses the adapter plate 210 against the compression spring 222.

[0048] The guide member 221 can be a guide shaft fixed to the support plate 230 and cooperate with a linear bearing fixed to the adapter plate 210 to slidably mount the adapter plate 210 to the support plate 230. A limiting block 223 is generally installed at the end of the guide member 221 away from the support plate 230, which can limit the adapter plate 210 and prevent it from detaching from the guide member 221. Furthermore, the limiting block 223 holds the adapter plate 210 against the compression spring 222 to ensure that the compression spring 222 remains compressed. In this way, the compression spring 222 can provide an elastic preload to ensure that the support plate 230 can elastically float relative to the adapter plate 210. More specifically, at least two guide members 221 are generally provided to better position the adapter plate 210 between the adapter plate 210 and the support plate 230. The limiting block 223 can be elongated and connected to at least two guide members 221 respectively.

[0049] It should be noted that in other embodiments, in order to achieve elastic floating of the support plate 230 relative to the adapter plate 210, the elastic floating component 220 may also adopt other structures. For example, multiple springs or sheets may be directly connected between the support plate 230 and the adapter plate 210.

[0050] Furthermore, in this embodiment, a stop screw 224 is provided on the limiting block 223, and the stop screw 224 passes through the limiting block 223 and abuts against the adapter plate 210. The stop screw 224 can be screwed in or out, thereby pressing the adapter plate 210 and adjusting the compression amount of the compression spring 222. In this way, the preload of the compression spring 222 can be adjusted as needed, thereby adjusting the degree of elastic floating.

[0051] The adsorption element 240 is connected to a negative pressure device (not shown) and adsorbs the electrode sheet by negative pressure adsorption. Therefore, the adsorption and release of the electrode sheet can be quickly achieved by controlling the on / off state of the negative pressure device.

[0052] Please refer to the following: Figure 4 In this embodiment, the adsorption member 240 includes a planar suction plate 244, and the surface of the planar suction plate 244 is provided with a plurality of adsorption holes 2441. The adsorption holes 2441 are connected to a negative pressure device, so a negative pressure can be formed on the surface of the planar suction plate 244 to adsorb the electrode. Since the surface of the planar suction plate 244 is provided with a plurality of adsorption holes 2441, the planar suction plate 244 can adsorb the electrode over a wider range of positions, thus making it suitable for electrode of more shapes and sizes.

[0053] In addition, please see Figure 5 In another embodiment, the adsorption member 240 includes a base plate 241, a suction cup 242, and an electrode suction block 243. The electrode suction block 243 is installed at one end of the base plate 241, and the suction cup 242 is embedded in the base plate 241.

[0054] The base plate 241 can be connected to the support plate 230 by screws, and a mounting groove can be opened on it for mounting the suction cups 242. Multiple suction cups 242 are generally provided, capable of adsorbing the main body of the electrode sheet, while the tab suction blocks 243 are used to adsorb the tabs of the electrode sheet. Similarly, the surface of the tab suction blocks 243 has multiple through holes (not shown in the figure), and the suction cups 242 and the through holes are all connected to the negative pressure device.

[0055] In the aforementioned conveying device 10 and stacking equipment, during the stacking operation, the adsorption mechanism 200 picks up the electrode sheets, and the driving mechanism 100 drives the adsorption mechanism 200 to reciprocate between the picking position and the stacking table, thereby stacking the electrode sheets sequentially on the stacking table. Because a damping element 310 is provided between the adsorption mechanism 200 and the driving end of the driving mechanism 100, and the damping element 310 can apply damping force to reduce vibration, even if the driving mechanism 100 moves at high speed during the stacking process, the vibration generated by the adsorption mechanism 200 will be significantly reduced compared to a traditional stacking robot. Therefore, the adsorption mechanism 200 and the electrode sheets it picks up can maintain high stability during high-speed stacking, thereby helping to improve stacking accuracy.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
